Abstract
The utility model relates to mechanical equipment for shipbuilding, in particular to an extra-large connecting nut for a ship, such as the loading and unloading device of a rudder blade, a rudderstock threaded connection nut, a hydraulic pressure nut and the like. The loading and unloading device comprises a hydraulic pressure hoisting platform the top part of which is fixedly connected with a tray supporting plate; the tray supporting plate is supported with a nut tray rotatably by a ball; the rotating center position of the nut tray is movably provided with a tray rotating core shaft which is fixedly connected with the tray supporting plate. The utility model is capable of conveniently screwing the threaded nut or the hydraulic nut into a threaded rod safely and effectively or pressing threaded nut or the hydraulic nut into a connecting rod.
Description
Technical field
The utility model relates to the shipbuilding plant equipment, relates in particular to super large attaching nut peculiar to vessel, as the be threaded handling instrument of nut, hydraulic nut etc. of rudder blade, rudder stock.
Background technology
Fast development along with shipping industry, the carrying capacity and the quantity of boats and ships constantly increase, and attaching nut peculiar to vessel is the most common part of ship machinery, and wherein not general size and all bigger ultra-large type nut of weight are exactly a typical example as the attaching nut of rudder blade in the boats and ships and rudder stock.
Rudder blade is one of vitals of boats and ships, is used to control the direction of ship running, is fixedly connected with rudder stock on the rudder blade, rotates the moment of rudder blade by the rudder stock transmission, and rudder blade and rudder stock are generally by being threaded or hydraulic nut is connected and fixed.Large ship centered rudder shank diameter generally reaches the hundreds of millimeter, thereby reach the hundreds of kilogram sometimes with the quality of the supporting nut of rudder stock, rely on manpower to rotate on the rudder stock it not only time-consuming, and be not easy the identical screw-in rudder stock of nut, or be pressed into rudder stock, and labour intensity is big, and efficient is very low, there is very big potential safety hazard again, still do not have solution preferably at present.
The utility model content
At the above-mentioned deficiency of existing in prior technology, technical problem to be solved in the utility model is will provide a kind of can easily screw nut or hydraulic nut be screwed in screw rod or be pressed into connection rod member and super large nut hydraulic loading-unloading device peculiar to vessel safely and efficiently.
In order to solve the problems of the technologies described above, super large nut hydraulic loading-unloading device peculiar to vessel of the present utility model, comprise hydraulic elevator platform, the top of this hydraulic elevator platform is connected with the tray supporting plate, by the ball rotatably support nut pallet is arranged on this tray supporting plate, the center position of this nut pallet is equipped with pallet rotation mandrel versatilely, and this pallet rotation mandrel is fixedly connected on the tray supporting plate.
After adopting said structure, owing to adopt hydraulic elevator platform support tray supports plate, by the oil mass in the hydraulic cylinder oil pocket in the control hydraulic elevator platform tray supporting plate is moved up and down, thereby hold up or fall super large nut to be loaded and unloaded, make this super large nut steadily, exactly near or break away from the connection rod member be housed to, the loading and unloading of nut are easy and convenient, alleviated the labour intensity of nut loading and unloading greatly.Again owing to ball and fixedly connected pallet rotation mandrel are arranged at tray supporting plate upper support, when the nut support pan arrest plays nut when waiting to screw in screw rod, gently the rotating nut pallet makes it rotate around pallet rotation mandrel again, and nut placed on it is screwed on the predetermined screw flight reposefully, at last more directly with nut screwing clamping on screw rod, inclination, the slip phenomenon of super large nut can not take place, whole cargo handling process is easy and convenient, not only have simple and reasonable, maneuverable advantage, and the characteristics of highly effective and safe are more arranged.
Adopt another remarkable advantage that said structure brought be can not only be convenient and swift, safe the female huge nut of loading and unloading, the huge hydraulic nut of loading and unloading that can also be safe and efficient, rely on the powerful hydraulic thrust of hydraulic elevator platform, the hydraulic nut that promotes the nut pallet and be placed on it, make the hydraulic nut axially-movable, and be installed on the predetermined parts.
Pallet rotation mandrel is one to have the Allen bolt of ladder.
The inside of hydraulic elevator platform is equipped with oil pump.
The exterior arrangement of hydraulic elevator platform has oil pump.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model super large nut loading and unloading peculiar to vessel device is described in further detail.
Fig. 1 is the structural representation of a kind of specific embodiment of the utility model super large nut peculiar to vessel hydraulic loading-unloading device.
The specific embodiment
In super large nut hydraulic loading-unloading device peculiar to vessel as shown in Figure 1, the top of hydraulic elevator platform 3 is the tray supporting plates 7 that are connected with hydraulic cylinder piston, be provided with ball grooves in the form of a ring on tray supporting plate 7 and the corresponding with it nut pallet 6 relative two sides, this ball grooves is built-in with plurality of balls 5, center position at nut pallet 6 is equipped with pallet rotation mandrel 8 versatilely, this pallet rotation mandrel 8 one has the Allen bolt of ladder, it fixedly is fastened on the tray supporting plate 7, makes nut pallet 6 movablely to rotate like a cork on tray supporting plate 7 around pallet rotation mandrel 8.
The exterior arrangement of hydraulic elevator platform 3 has oil pump 1, the bottom of hydraulic elevator platform 3 is equipped with inlet nozzle 2 and draining valve 4, inlet nozzle 2 is connected with the oil transportation outlet of oil pump 1, draining valve 4 is used to the pressure release of draining the oil, during work, the hydraulic oil of oil pump 1 output is in inlet nozzle 2 enters the oil pocket of hydraulic elevator platform 3 inside, by hydraulic drive tray supporting plate 7 is risen, nut pallet 6 placed on it and hydraulic nut (not drawing among the hydraulic nut figure) also move up thereupon, and near predetermined rudder stock, continue to pump into hydraulic oil then, make fastening being installed on the rudder stock of hydraulic nut.Install the back and open draining valve 4, the release of pressure of draining the oil, tray supporting plate 6 descends.
Enumerated a kind of preferred implementation of the present utility model above, but the utility model is not limited thereto, and can also make many improvement and conversion, merges as oil pump and hydraulic elevator platform, inside at hydraulic elevator platform is equipped with oil pump, becomes monolithic construction.These conversion and improvement all fall in the protection domain of the present utility model.
